stefan problems
 
Hye all,

I am working on tracking the freeze front propagation in two dimensions. My geometry consists of a rectangular plate with water intitially at 37 degrees and brought incontact with -163 degrees. I need a code to track the freeze front propagation or a method by which I can solve such a problem.

Thankyou

I may be totally lost in this one but this reminds me of a class project I did N years ago. Actually I had to melt something...

If I remember correctly, I just wrote a finite-difference code for this. That was considered accurate enough for a class project.

Stefan problems (pure heat conduction) can be solved by finite difference easilly. The front varies equal in two dimensions. Problems with natural convection are most difficult cause it do not happens.
